Use of Enhanced F keys in the keyboard

The IE6 with MSN Toolbar seemed to understand at least some of the Enhanced F
keys in keyboards like Optical Desktop with Fingerprint Reader (Enhanced
F-enabled keyboard w/Fingerprint Reader on the left).

Sadly, IE7 all-around lovely preview Beta 2... seems to totally ignore the
Enhanced F-keys Whereas I can think of at least:
New - Opens a new Tab,
Open - Input URL and open it in a new Tab,
Save, Print, Help - doing what's "on the tin",
"Undo" and "Redo" with left & right arrows would obviously be candidates for
BACK and FORWARD functions!
Probably Send function could be used for sending a Link to a mail recipient.

I wonder if Microsoft still plans to support these keys in the future, or is
it a dead end?

It's frustrating to not be able to use these useful keys, and see the people
who stick with F (old/linux-style) still prevail.
